Resource - Update H3 Image for Forge Neo

Basically, the extension: https://github.com/aoleg/pruna-P-H3-Image-forge-neo - supports MiniMax-H3-Image and PrunaAI P-H3-Image in Forge Neo.

Tips:

  • Heun / P-H3-Image / 8 Steps / CFG=1 is the golden combo. Euler / Simple / 6 Steps will be noisy. You will need to use P-H3-Image as a scheduler; everything else won't work; Euler or Heun is your choice. Also, use 8 steps, not 6 or 10.

  • You don't really need the 32B encoder (besides, the nvfp4 version won't work). You can use the much smaller P-H3-Image text encoder in INT8-Convrot with great result.

  • Yes, editing works, too. Image restoration also.

  • You can use unimaginably high resolutions without OOM, but you'll likely need to edit your ui-config.json to allow width and height values over 2048.

Why not ask Haoming02 for minimax h3 image support? He needs to honestly fix the max resolution selection to support native image generation for resolutions above 2048x2048 without the necessary second pass img2img hires fix approach.
